It can be used as a door stop alarm and door stopper, prevent the bad guys into. A protector around you. Can be used in home and travel.
Very loud shrill that would definitely scare someone away with 120db alarm.
No installation required.Each requires one 9v battery(Not include).Portable and easy way to add peace of mind when traveling or working alone.
Simply place the alarm behind any door ,very convenient to take with you when travel or stay indoor alone. A really must have around you. Especially for girls.
